OpenCL not available after suspend/resume cycle with driver 525.78.01-0ubuntu0.22.04.1 and Kernel 5.15.0-58

I’m using the driver and kernel version specified in the topic title, in Mint 21, based on ubuntu 22.04, with 2 GB Geforce GTX 1050 .

After a suspend/resume cycle those applications which exploit OpenCl (such as clinfo and darktable) report that OpenCl is not available. The same issue might exist with the previous driver (515.86.01) and a previous kernel (5.15.0-57). work around is to unload and reload nvidia_uvm

Similar issue with 595 driver on MX 23 (Debian derivative) . No audio on initial cold boot, openCL works in darktable, reboot, audio is back, no openCL.
